Abstract

EL INVENTO CONCIERNE A UN MONTAJE PARA EL COMBUSTIBLE NUCLEAR ESPECIALMENTE APROPIADO PARA USAR EN LA LOCALIZACION PERIFERICA DEL NUCLEO DONDE PUEDE OCURRIR EL LANZAMIENTO A CHORRO DEL LIQUIDO REFRIGERANTE A TRAVES DE LA ESTRUCTURA DEFLECTORA DEL NUCLEO. ADEMAS DE LAS REJILLAS SOPORTE DE LAS VARILLAS DEL COMBUSTIBLE Y FISICAMENTE SEPARADAS DE ELLAS, EL MONTAJE PARA EL COMBUSTIBLE (16A) INCLUYE REJILLAS ANTIVIBRACION (68) CADA UNA DE ELLAS CONFIERE UN SOPORTE DE AMORTIGUAMIENTO PARA LAS VIBRACIONES A LAS VARILLAS DEL COMBUSTIBLE (48A) CERCA DE LA PERIFERIA EXTERIOR DEL MONTAJE PARA EL COMBUSTIBLE, Y ES DE CONSTRUCCION DE TRABAJO DESCUBIERTO QUE DEFINE UNA VENTANA (76) A TRAVES DE LA CUAL SE EXTIENDEN TODAS ESTAS VARILLAS DE COMBUSTIBLE SOBRANTE (48B) SEPARADO MAS LEJOS DEL INTERIOR DE LA PERIFERIA EXTERIOR DEL MONTAJE DEL COMBUSTIBLE.
